6 minutes in my microphone stopped recording (it updated the firmware?), so I will have to redo this.
On the positive side, I will now take a look at what I did, clean up the code, and script my stream so it is clearer.

Not yet. I think in the long run resources will allow for easier development of custom tools inside #godot, but #json would probably make it easier to make cloud save or external scripts to process data. For online games I would probably go json.

The course uses the code from the inventory system, but at the beginning you are given a zip folder containing the code for it. You do not need the separate course to have all the files needed for the horror game.
You can always look at the code and try to understand what it does by yourself.

By Ascension I mean the game resets, but you get some permanent upgrades between runs.
